IMPROVEMENT IN SCREW HEDDLE EYES 0R HOOKS FOR HEDDLE-FRAMES.

Specification forming part of Letters Patent No. 204,881, dated June 18,1878 application filed March 30, um.

To all whom it may concern:

Be it known that 'I, DARIUS O. BROWN, 0 Lowell, in the county ofMiddlesex and State of Massachusetts, have invented an Improved ScrewHeddle Eye or Hook for Mounting Heddles of Looms, of which the followingis a specification:

This improvement relates to the manner of constructing the eyes or hookswhich are inserted in the upper and lower shafts of the several leavesof heddles, to which eyes or hooks the cords or straps are attached bywhich each leaf is suspended and worked. Each of these screw-eyes isusually attached to the upper or lower shaft of the heddle in themiddleof its thickness by screwing the metallic shank of the eye or hookinto the wooden shaft in the plane of the heddle-leaf, with the eye orhook of the same projecting above and below the leaf to which the cordsor straps are attached.

In making the heddles of twine, each strand or twine of the heddle isattached at both the top and bottom of the leaf to a small cord calledthe rig-band, either by knitting or knottin g, which rig-band is placedat the middle of the thickness of each shaft, and extends the wholelength of each leaf from end to end. Now, as this rig-band occupies themiddle position on both the top and bottom of the leaf, the insertion ofthe screw eyes or hooks into the shaft, as shown, pushes the rig-band toone side of a central position in the leaf, which raises or depressesthe eyes or mails, which are connected with those twines or cords, sothat they are not in line with the other eyes or mails in that leaf,which seriously interferes with the proper action of the heddles inweaving, and causes those eyes or mails thus disturbed or moved out oftheir proper position to receive unnecessary strain or wear, whichcauses them to be prematurely worn out or broken.

To avoid this result is the purpose of this invention, which consists inmaking the shanks of the screw eyes or hooks, at or near the point wherethey enter the top or bottom surfaces of the shaft of the heddle-leaves,with a recess or offset, which will permit the rig-band to occupy acentral position on the shaft, while the eyes or hooks also occupy acentral position to the leaves, and thus entirely obviate the defeetbefore named, and yet be as convenient as the screw-eyes and hooksbefore in use.

In the drawings, Figure 1 is a view of thescrew-eyes in ordinary use.Figs. 2 and 3 are two views of the improved screw-eyes, with the offsetfor the rig-band 'at right angles to the plane of the eye. Figs. 4 and 5are two views of the improved screw-eye, with the plane of the eye at aright angle to that of the eyes shown in Figs. 2 and 3, and in Fig. 4the screweye is shown as inserted in the heddle-shaft in position foruse. The dotted lines in this figure show a screw-hook inserted in thesame place, excepting that the plane of the hook would generally beparallel to the plane of the leaf of heddles instead of transverse toit. Figs. 6 and 7 show hooks that are to be used instead of eyes when itis desired to mount the heddles with straps instead of cords.

The hooks and eyes are made of wire in the usual way, and provided withscrewed shanks to screw into wood, as is shown in the drawings, by whichthey are secured to the heddlesha-ft, as seen in Fig. 4, and at thepoint at which the shank crosses the rig-band a it is provided with arecess or offset, 12, which permits the rig-band to retain its centralposition on the heddle-shaft, as is shown.

As the hook or eye is inserted into the heddle-shaft by screwing it intoplace, the plane of the eye or hook may be placed either par-' allelwith the plane of the leaf or at a right angle to this; and,in orderthat the shank may not displace therig-band,itmay be well to make asmall recess or countersink, c, in the shaft, to enable the offset orrecess 1) to come beneath the rig-band, as seen in Fig. 4.

What I claim as my invention is 1. The improved hook or eye made with ascrew-shank and an offset or recess in the shank to receive therig-band, and adapted to operate substantially as described.

2. The improved hook or eye made with a screw-shank and with an offsetor recess in the shank to receive the rig-band, as described, incombination with the shaft of a leaf of heddles, substantially asdescribed.

Executed March 27, 1877.
